Regional development & urban planning

Security of tunnels is a recent topic in planning. Because of the high costs of increasing security in existing tunnels or to build new tunnels, simulations of individual movement are appropriate tools to analyse the infrastructural design and planned measures of e.g. security stations. Incidences like fire or explosion could be simulated without the need for large experiments.

For a situation with a fire at the machine of a TGV situated in a tunnel an evacuation simulation was developed. Agents, as representatives for travellers, are modelled with rich behaviour concerning the movement, the recognition of signs and temperature, reactions to smoke in the environment and communication concerning sharing their experiences. Variants of different infrastructual layouts of tracks, security galleries, security areas and doors were studied using the simulation of about 750 passengers leaving the train, searching their way to a parallel secure gallery.

The results, as e.g. travel times, evacuation times, densities and amount of dead passengers are used within the whole decision process about the planned tunnel and it's elements.

The amount of travellers using trains is still increasing. Larger train stations become more and more shopping center with railroad access. It is to be expected, that these developments will lead to bottlenecks within the existing infarstructure. To support the planning and decision process concerning the design and realization of measures simulation, especially micro simulations of pedestrians, are appropriate tools to analyse the impacts of planned measures.

To analyse different development scenarios for the SBB main station Lucerne a agent based micro simulation of the entire station was developed based on an existing pedestrian simulation. Using existing data of travellers, new collected data of pedestrian amounts at all entrance and exists of the station and the timetable a complete origin destination matrix was developed. On this basis 16'000 agents were simulated during the time period 4:20pm - 6:40pm.

As results e.g. travel times, densities (LoS) and loads of elements as e.g. stages and escalators were calculated. Bottlenecks were identified as well as obstacles. Recommendations for measures were made and the impacts of these measures analysed.
